This invention relates to improvements in air cooling systems.

The primary object of this invention is to provide a device of the above mentioned character adapted to cool the entire area of a room of a house or building.

A further object of this invention is to provide a device of the above mentioned character adapted to draw the air over a plurality of wet baffles to moisten the same and thereby raise the humidity of the room to which it is injected.

A still further object of this invention is to provide a device of the above mentioned character which employs a paddle wheel fan mounted in a casing in such a manner as to reduce the large amount of noise occurring from vibrations due to the fast rate of speed the fan rotates.

A still further object of this invention is to provide a device of the above mentioned character. including a fan blower independently operated from the water circulating system.

Other objects and advantages will be apparent during the course of the following description in which like reference characters designate like parts throughout the same and in which I Figure 1 is a front elevational view of the invention showing the fan blower and showing the air outlet which extends the full width of the casing proper;

Figure 2 is a side elevational view of the same showing the manner in which the fan blower casing is supported;

culating system and the casing partly in sect1on in which they are positioned; and

Figure 7 is a front elevational view of the particular form of the battle over which air is passed to moisten the same.

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 10 designates a pair of opposite base bars having a pair of opposite vertical standards 11 fas tened thereto as at 12 by bolts passing therethrough having nuts on their ends to hold the same in place.

The opposite vertical standards are braced by opposite brace bars 13 at their upper and lowermost portions while the opposite cross brace bars 14; are centrally positioned in respect to the brace bars 13 to form a bearing for the paddle wheel which will be described more fully during the course of the descript1on. The pair of opposite standards 11 are held in opposite relation with each other by end brace bars 15 fastened thereto by bolts or other fastening means passing through the ends thereof.

A drum 16 is sandwiched between the op- 1 posite vertical standards 11, having opposite side walls 17 and an air outlet 18 formed tangentially therewith. The side walls 17 of the drum 16 are provided with openings for the inlet of air covered with a piece of wire mesh screen 21 to keep dirt and other foreign matter from the air which is eX- hausted through the outlet 18.

A rotary shaft 19 is mounted eccentrically and extends transversely through the drum l6 and wire mesh 21 and has its ends journaled in an antifriction bearing rotatably mounted in the ball bearings 22 of the ball bearing housing 23. Rigidly mounted upon the rotary shaft 19 is a pair of opposite carriage wheels comprising a hub 24; of wood or other material and an internal liner sleeve 25 27 extending radially from the hub 24 and terminating in the rim 28 which is provided with a rubber the 29 on the periphery there of forming a resilient binding for holding the parts of the wheel more firmly together. Mounted to rotate with the opposite carriage wheels and fastened adjacent the outer ends of the radially extending spokes 27, are a plurality of fan blades 30 fastened to the spokes 27 by bolts 31 passing through the spokes 27 and the fan blade 30.

An electric motor 32 is provided for transmitting power to the band pulley 33 keyed upon the shaft 19 by the longitudinally extending key 34, best shown in Fig. 5 of the drawings. A power belt 35 passes around the band pulley 33 and the pulley 36, secured to the shaft of the electric motor 32, as shown in Fig. 6.

The apparatus thus far described constitutes the fan blower mechanism associated with the air moistening apparatus which will be described in the lines to follow.

It is to be understood that the fan blower 17 may be positioned on the outside of a building with its tangential opening 18 proj ecting through the side wall for distributing a draft of fresh air therethrough.

The apparatus for moistening the air includes vertical standards 37 mounted within the casing 38 and positioned in the path of the opening 39 formed in the end wall of the casing 38 as best shown in Figs. 6 and 7. A plurality of battle plates 40 of different widths extend laterally and downwardly from the vertical standards 37 and are provided with apertures 41 through which water passes and commingles with the air drawn through the opening 39.

. A tubular spraying pie 42 having apertures 43 is mounted upon the upper longitudinal edge of the vertical standards 37 and is supplied with water through the feed pipe 44 which is connected to the rotary pump 45 drawn through the medium of an electric motor 46 by the belt 47 passing around the pulley 48 of the rotary pump and the pulley 49 of the electric motor 46.

A drip pan 50 is mounted below the baffle plates 40 to catch the water dripping from the baffle plates 40 and through the apertures 41 formed therein. The drip water is fed back to the rotary pump 45 through the feed pipe 51 and is again circulated through the igboistening system and over the baffle plates For a consideration of the operation of the device, attention is just called to the showing in Fig. 6. The electric motor 32 is started to effect the rotation of the rotary shaft 19 and the fan blades 30 within the drum 16, which creates a suction of air through the wire screen 21 mounted in the side walls 17 of the drum 16.

It is to be understood that the fan blades 30 are rotated clockwise thereby forcing the air drawn through the wire screen 21 out of the tangential outlet 18, projecting through the side wall of the housing 38.

The air drawn into the housing 38 passes through the opening 39 and commingles with the atomized particles of water falling from the apertured baffle plates 40. The water is circulated over the baffle plates 40 by a circulating system including the motor driven pump 45 fed by the drip pan 50 through the fe'ed'pipe 51. The water is pumped upwardly through the pipe 44 and is forced through the apertures 43 formed in the longitudinal spray pipe 42. g

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangements of parts may be re sorted to without departing from the spirit of my invention or the scope of the subj oined claim.

Having thus described my invention, I claim:

A cooling and Ventilating system of the character and for the purposes described comprising a walled casing having an unobstructed opening in one of its walls constructed and adapted for the admission of atmospheric air from the exterior thereof, an outlet opening in the opposite wall for the escape of air therethrough, a series of perforated baiile plates adjacent to said first named opening, means for spraying water over and through said plate, and power driven means for producing a forced draft of air through said enclosure, said means including a drum having screened side inlets, and a rotary power driven fan within said drum, said drum being of helicoidal form with a tangential outlet air shaft communicating with the outlet of the casing, the elements recited arranged and adapted to delivera forcible current of pure moistened .air from the interior of said casing to a receptiveenclosure.

In testimony whereof I afiix my signature.

GEORGE A. PETERSON.
